.SH NAME
pdftoppm \- Portable Document Format (PDF) to Portable Pixmap (PPM)
converter (version 4.04)
.SH SYNOPSIS
.B pdftoppm
[options]
.I PDF-file PPM-root
.SH DESCRIPTION
.B Pdftoppm
converts Portable Document Format (PDF) files to color image files in
Portable Pixmap (PPM) format, grayscale image files in Portable
Graymap (PGM) format, or monochrome image files in Portable Bitmap
(PBM) format.
.PP
Pdftoppm reads the PDF file,
.IR PDF-file ,
and writes one PPM file for each page,
.IR PPM-root - nnnnnn .ppm,
where
.I nnnnnn
is the page number.
If
.I PPM-root
is \'-', the image is sent to stdout (this is probably only useful
when converting a single page).
.SH CONFIGURATION FILE
Pdftoppm reads a configuration file at startup.  It first tries to
find the user's private config file, ~/.xpdfrc.  If that doesn't
exist, it looks for a system-wide config file, typically /etc/xpdfrc
(but this location can be changed when pdftoppm is built).  See the
.BR xpdfrc (5)
man page for details.
.SH OPTIONS
Many of the following options can be set with configuration file
commands.  These are listed in square brackets with the description of
the corresponding command line option.
